Quick answer: Yes. A compatible Samsung USB-C Power Delivery charger can safely charge an iPhone. The iPhone controls the power it accepts, so a 25W or 45W adapter does not force the full rating into the phone. The cable and iPhone model determine what you need.
Samsung charger and iPhone compatibility
| iPhone | Cable | Practical adapter choice |
|---|---|---|
| iPhone 15 and iPhone 16 families | USB-C to USB-C | A compatible USB-C PD adapter rated 20W or higher |
| iPhone 17, 17 Pro and 17 Pro Max | USB-C to USB-C | A compatible 40W-or-higher adapter is needed for Apple's fastest stated wired result |
| iPhone Air and iPhone 17e | USB-C to USB-C | 20W or higher for Apple's stated fast-charge setup |
| iPhone 14 and earlier | USB-C to Lightning | A compatible USB-C PD adapter, normally 20W or higher for fast charging on supported models |
Will a Samsung 25W charger work with iPhone?
Yes, when the Samsung adapter provides USB-C Power Delivery and you use the correct cable. It is a sensible choice for many iPhones, but it cannot provide Apple's fastest stated wired result for iPhone 17, iPhone 17 Pro or iPhone 17 Pro Max because Apple associates that result with a 40W-or-higher adapter.
Check the current Samsung 25W USB-C PD adapter listing and select a cable that matches your iPhone.
Will a Samsung 45W charger work with iPhone?
Yes, a compatible Samsung 45W USB-C PD adapter can charge USB-C iPhones. A higher adapter rating is only available power; the iPhone negotiates what it can use. For iPhone 17, 17 Pro and 17 Pro Max, Apple says a 40W-or-higher adapter with a USB-C cable can reach up to 50% in around 20 minutes under its test conditions. Actual results vary with temperature, battery level, settings and use.
Compare the active Samsung 45W adapter options. Some variants are adapter-only and others include a cable, so read the complete variant name before ordering.
Is it safe to use a Samsung charger with an iPhone?
Brand mixing is not the main safety issue. Use an undamaged adapter that supports the required USB-C charging standard, an appropriate cable in good condition and a secure wall socket. Stop using equipment that becomes unusually hot, has exposed wire, repeatedly disconnects or shows physical damage.
Apple says compatible third-party USB-C adapters can charge iPhone when they meet applicable safety standards. Samsung describes its 45W adapter as compatible with USB-C devices, although charging speed varies by device.
What cable do you need?
- iPhone 15 and later: use USB-C to USB-C.
- iPhone 14 and earlier: use USB-C to Lightning with a USB-C adapter.
- For a 45W setup: use a USB-C cable that supports the required charging profile; do not assume every cable has the same power capability.
See the Type-C collection for current cable options.
Samsung 25W or 45W for an iPhone?
- Choose 25W for a lower-priced compatible option for many iPhones.
- Choose 45W for iPhone 17 models when you want the adapter wattage required for Apple's fastest stated wired result, or when you also charge compatible higher-power USB-C devices.
- Do not pay for extra wattage expecting every iPhone to charge at the adapter's full rating.
